Summary: Green grass, wet, standard field work, all seems well

I arrived at about 12:20 PST. It was cool and overcast with the sun peeking through a couple of times. The trees still have some green leaves â€“ not unusual for this time of year and about half are turning yellow/brown. The ground is wet and the grass it about 2-5cm tall. The pond level hasnâ€™t changed much â€“ still a little more than about half full. Mushrooms coming up here and there. There is dense, lush growth of weeds around most of the ant mounds.

I collected met, flux, camera images, DHB, soil moisture, well levels and the FD data. All seemed well.
The Tower 7500: 455.6ppm CO2, 502.5mmol/m3 H2O, 99.9kPa, 13.7C, 103.6SS
The Floor 7500: 457.2ppm CO2, 523.3mmol/m3 H2O, 99.4kPa, 14.5C, 101.3SS

I got all prepared to swap the fan on the Floor HMP but discovered that the fan had started running again. I wiggled the wire a little and it kept going. Donâ€™t fix what aint broke.

I turned the electric fence on around the tower. It powered right up and seemed to be working well. I didnâ€™t try the charger on the soil co2 fence.

I left at about 14:40 PST
